Can you not tell your DH to give the guys a few days to a weeks notice that they need to have someone else take their car to work so you can keep yours? If they're supposed to take turns, this shouldn't be that big of a deal.

Sounds like you and the kids need to get out of there for awhile.

I agree, I would be telling DH to give the guys some warning to make other arrangements, because you need the car for the good of the family.

I am sure that they can find another car to use between the 5 of them. What the heck did they do before you guys got there?!?
